What is C01D6?

The diagnostic trouble code C01D6 indicates an issue with the traction control system in your vehicle. This code is predominantly seen in models like the 2014-2018 Chevrolet Silverado, 2015-2019 GMC Sierra, and other GM vehicles equipped with similar systems. When this code appears, it typically signifies that the traction control system has detected a malfunction that affects the vehicle's stability control features. In simpler terms, the traction control system helps prevent wheel spin during acceleration by applying brakes to individual wheels, which enhances grip on slippery surfaces. If you ignore this code, it could lead to diminished vehicle control, especially in adverse weather conditions. Drivers may notice the traction control light illuminating on their dashboard, which often prompts concern about vehicle safety and performance. Addressing this issue promptly is crucial for maintaining optimal driving conditions. In some cases, you might also experience a decrease in fuel efficiency or acceleration issues, as the system may be continuously engaging to compensate for the fault. It’s essential to have a qualified technician diagnose the underlying issues associated with this code to prevent further complications in the vehicle’s performance.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C01D6 is present:

  • The traction control light stays illuminated on the dashboard, indicating a malfunction in the system.
  • You may experience reduced acceleration, particularly when driving on wet or slippery roads, due to the system's inability to regulate wheel spin effectively.
  • Drivers might notice a sudden loss of traction when starting from a stop, causing the vehicle to slip or skid unexpectedly.
  • There may be a noticeable decrease in fuel efficiency, as the vehicle's computer works harder to correct traction issues.
  • In some cases, the vehicle may enter 'limp mode,' where acceleration is limited, preventing the vehicle from performing adequately.

Possible Causes

Most common causes of C01D6 (ordered by frequency):

  1. The most common cause of C01D6 is a faulty wheel speed sensor, which accounts for around 40% of cases. This sensor monitors the speed of each wheel and relays information to the traction control system.
  2. Another frequent cause is damaged wiring or connectors related to the traction control system, which can disrupt communication between components. This is typically seen in vehicles with higher mileage or poor maintenance.
  3. A malfunctioning ABS module is another potential cause. Since the ABS system is closely linked to traction control, any issues here can trigger the C01D6 code. Regular inspections can help prevent this.
  4. Less common but serious causes include a failing powertrain control module (PCM), which can result in widespread vehicle performance issues if not addressed.
  5. In rare cases, software glitches in the traction control system can lead to this error. Updates from the manufacturer may be needed to resolve these problems.
